DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used in, for example, audio equipment, video equipment, information equipment, communication equipment, measuring equipment, etc., and records on a disc such as a CD or DVD.
The present invention belongs to the technical field of a disk recording medium processing apparatus for performing processing such as reproduction, and particularly to the technical field of a disk recording medium processing apparatus capable of setting a plurality of disks and being compact.

[0002]

2. Description of the Related Art For example, in audio equipment, various disk recording / reproducing apparatuses using a CD on which a large number of music pieces are recorded have been developed. As one of such conventional disk recording and reproducing devices, there is a tray type disk recording and reproducing device. In this tray-type disc recording / reproducing apparatus, a tray for holding and transporting a CD advances outside the apparatus main body, a CD is placed on the advanced tray, and then the tray is transported to a pickup position of a traverse unit in the apparatus main body. ing. In such a case, many tray-type disc recording / reproducing apparatuses have been developed in which the trays are stacked in a plurality of stages so as to support a plurality of CDs.

As another conventional disk recording / reproducing device, there is a slot-in type disk recording / reproducing device. This slot-in type disk recording / reproducing device
A CD insertion slot comprising a slot is provided in the apparatus main body. By inserting a CD into this CD insertion slot,
The CD is pulled into the apparatus main body and set at the pickup position of the traverse unit. In this case, a plurality of CDs are sequentially inserted from one CD insertion / extraction port and stored in the apparatus main body, and C set by the user as desired is set.
A slot-in type disk recording / reproducing apparatus in which D is set at a pickup position of a traverse unit by a CD change mechanism, and a slot-in type disk recording / reproducing apparatus in which the traverse unit is compact have been developed. .

[0004]

However, in the above-mentioned conventional disk recording / reproducing apparatus of the tray system, when the trays are stacked in a plurality of stages so as to support a plurality of CDs, each of the trays has a considerable thickness. For this reason, there is a problem that if a plurality of stages are stacked, the entire apparatus becomes large. In addition, in this tray type disk recording / reproducing apparatus, it is difficult to hold the disk in a vertical position when holding the disk, and particularly, the vertical position of the 8 cm disk cannot be achieved. A compact traverse unit such as that used in a portable slot-in system cannot be used, and the device is inevitably increased in size, which requires a large installation space. In addition, since the tray protrudes to the front of the apparatus main body, there is a problem that there are many restrictions on an installation space, a design, and the like.

On the other hand, the slot-in type disk recording / reproducing apparatus does not have the above-mentioned restriction due to the fact that the tray advances to the front of the apparatus main body as in the case of the tray type. From one CD to another stored in the main body of the apparatus when recording or reproducing is performed for one CD.
In order to remove D from the apparatus main body or to replace another stored CD with another new CD, there is a problem that the apparatus becomes large and large.

Further, in this slot-in type disk recording / reproducing apparatus, for example, an 8 cm disk cannot be held in a vertical position. There is also the problem of being restricted.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a disk recording medium processing apparatus capable of easily taking out a disk stored in an apparatus main body. is there.

[0008]

In order to solve the above-mentioned problems, according to the first aspect of the present invention, a storage position at which a disk can be stored and a pickup position for processing the disk by a traverse unit are set. An apparatus main body, a slot-shaped disk insertion / extraction port provided in the apparatus main body, a disk holding / transporting means movably provided between the store position and the pickup position in the apparatus main body, A disk pushing means for pushing out the disk of the disk holding / transporting means toward the disk insertion / extraction port.

Further, according to a second aspect of the present invention, the disk pushing means contacts a peripheral edge of the disk to press the disk, and controls the disk contact and pressing of the disk pressing member. And a disk pressing control member.

Further, the invention according to claim 3 is characterized in that the disk pressing member includes a rotatable roller for pressing the disk in contact with the outer peripheral surface of the disk.

[0011]

In the disk recording medium processing apparatus of the present invention having such a configuration, the disk held by the disk holding / transporting means at the store position in the apparatus main body is moved toward the disk insertion / extraction opening by the disk pushing means. Can be extruded. This makes it possible to easily take out the disk inside the apparatus main body out of the apparatus main body. In particular,
When a plurality of disks are stored in the apparatus main body, any disk can be freely removed by operating the disk pushing means corresponding to the disk regardless of the state of other disks.

In particular, according to the third aspect of the present invention, even if the disc pressing member performs the pushing operation of the disc when the disc is pushed, the roller rotates relatively to the disc pushing member. Rubbing hardly occurs between the outer peripheral edge and the outer peripheral edge. Therefore, the disc is pushed out smoothly, and the load on the disc pressing member is reduced. In addition, since the rollers are rotatable, it is possible to respond flexibly regardless of the size of the disk.

A gear 95 is rotatably provided at one end of the power transmission switching arm 94. In this case, when the gear 95 rotates, a small predetermined frictional force (rotational load) is applied to the power transmission switching arm 94 (for example, the rotation shaft of the gear 95 and the rotatable shaft). A frictional force is applied between the supporting power transmission switching arm 94 and the bearing. The rotation of the intermediate pulley 92 is transmitted to the gear 95 at a reduced speed via a gear (not shown; lower side of the power transmission switching arm 94 in FIG. 13) that rotates integrally with the intermediate pulley 92. ing. The frictional force may act between the intermediate pulley 92 and the power transmission switching arm 94.

Further, an intermediate gear 96 is rotatably provided in the apparatus main body 2.

Then, the first motor is rotated so that the first and second rollers 17, 18 rotate in the direction of drawing the first and second CDs 8, 9 into the disk recording medium processing apparatus 1 in the state shown in FIG. Rotates, the rotation of the first motor becomes
First motor pulley 91, endless belt 93, intermediate pulley 9
The power is transmitted to the gear 95 via the second gear or the like. However, at this time, since the predetermined frictional force acts between the gear 95 and the power transmission switching arm 94 as described above, the gear 95 does not rotate, and the power transmission switching arm 94 is moved around the rotation shaft 92a. At 13, rotation is made in a counterclockwise direction. When the gear 95 meshes with the intermediate gear 96 by the rotation of the power transmission switching arm 94 in the counterclockwise direction, the power transmission switching arm 94 does not further rotate in the counterclockwise direction, so that the gear 95 rotates (rotates). When the rotation of the gear 95 is transmitted to the intermediate gear 96, the rotation of the first motor is reduced and transmitted to the first and second rollers 17 and 18. That is, the first motor pulley 91, the endless belt 93, the intermediate pulley 92, the gear 95, and the intermediate gear 96 constitute a drive system of the first motor for the first and second rollers.

In the state shown in FIG. 13, the first and second rollers 17 and 18 are rotated in the direction in which the first and second CDs 8 and 9 are pulled in from the disk recording medium processing apparatus 1. When the motor rotates, the gear 95 is similarly operated.
Since a predetermined frictional force acts between the power transmission switching arm 94 and the power transmission switching arm 94, the power transmission switching arm 94 rotates clockwise in FIG. 13 around the rotation shaft 92a. When the gear 95 meshes with the gear 126 which is always meshed with the gear 89d of the cam member 89 by the clockwise rotation of the power transmission switching arm 94, the power transmission switching arm 94 does not further rotate clockwise. 96 rotates (rotates), and the rotation of the gear 95
By transmitting the rotation to the cam member 89, the rotation of the first motor is reduced and transmitted to the cam member 89. That is, the first motor pulley 91, the endless belt 93, the intermediate pulley 9
2, by the gear 95 and the gear 89d of the cam member 89,
A drive system of the first motor for the cam member 89 is configured.

Are the first and second chucking control members 51, respectively.
Since the pressed pins 51b, 51b 'of 51' are not pressed, the first to fourth chucking pins 31, 32, 3
3, 34; 31 ', 32', 33 'and 34' are all shown in FIG.
It is set to the closed position shown in FIG.

When the user first turns on the main switch in the non-operating state of the disk recording medium processing apparatus 1, the cam position detecting section 89c of the cam member 89 is detected by the cam position detecting photo sensor, and the cam position detecting signal is output. Is input to the microcomputer. Based on the cam position detection signal, the microcomputer determines which gear of the first and second racks 80, 80 'is currently engaged with the gear 87a of the rack drive gear member 87, and determines whether the gear 87a It is determined which of the first and second tracks 6, 7 is the initial height position corresponding to the current track height position.

Next, in order to insert the first CD 8 of, for example, 12 cm into, for example, the first CD insertion opening 10 among the first and second CD insertion openings 10, 11 closed by the user, the first shutter 13 is opened. Turn on the operation key to open. Then, when the microcomputer determines that the rack drive gear member 87 meshes with the first rack 80 and determines that the initial height position of the traverse unit 23 corresponds to the initial height position on the first track side, the second microcomputer. The first rack slider 79 is moved to the first CD insertion / ejection port 10 by driving the motor. Then, since the projection 84 of the first rack slider 79 presses the pressed portion 108 of the power switching arm lock slider 105, the power switching arm lock slider 105 moves to the lock position as described above. Thereby, the gear 9
5 meshes with the intermediate gear 96, so that the rotation of the first motor can be transmitted to the first roller 17.

Further, since the end 85a of the pressing member 85 presses the pressed pin 51b of the first chucking control member 51 by the movement of the first rack slider 79, the first chucking control member 51 rotates. As a result, the chucking arms 35, 36, 37, 38 rotate, and the first to fourth chucking arms 35, 36, 37, 38 rotate.
The chucking pins 43, 44, 45 and 46 are shown in FIG.
CD standby position.

Then, when the first CD 8 is inserted into the first CD insertion / extraction port 10, the CD detection sensor detects the first CD 8, and the first motor rotates. Then, since the rotation of the first motor is transmitted to the first roller 17 and the first roller 17 rotates, the first CD 8 is pulled into the apparatus main body 2 and moves to the right side, that is, the store position A in FIG. It moves toward a regular position on a certain first CD holding and conveying member 21.

Then, the edge 8a of the first CD 8 is
As shown in (a), the first and second chucking pins 31 and 32 at the standby position come into contact with each other. Furthermore, the first CD8
Is retracted, the first and second chucking pins 3
1 and 32, while chucking the edge 8a of the first CD 8, is in the maximum open state shown in FIG. When the first CD 8 is further pulled in, the first and second chucking pins 31 and 32 move inward, and the distance between them decreases.

When the first CD 8 is retracted to some extent and reaches a predetermined position, the CD position is detected by a CD detection photo sensor, and the CD position detection signal is input to the microcomputer, and the microcomputer drives the second motor to rotate. I do. The rotation of the second motor is reduced and the rack drive gear member 87
The gear 8 of the rack drive gear member 87
7a to the first rack 80. As a result, the first rack slider 79 moves slightly toward the pickup position B (a predetermined amount). The fact that the first rack slider 79 has moved a little distance indicates that the position detection switch 1
When the position is detected by one of the microcomputers 09 and 110 and the position detection signal is input to the microcomputer, the microcomputer stops the second motor.

Since the projection 84 of the first rack slider 79 is separated from the pressed portion 108 of the power switching arm lock slider 105 by a slight movement of the first rack slider 79, the power switching arm lock slider 105 The unlocked position is set by the spring force, and the power transmission switching arm 94 is unlocked and becomes freely rotatable.
At this time, since the first motor is still rotating in the same direction, the power transmission switching arm 94 is held in a state where the power transmission system of the first motor is connected to the first roller 17, and the first roller 17 is Still rotating in the same direction, the first
Of the CD 8 to the regular position on the first CD holding / transporting member 21 is continuously performed.

When the first CD 8 further moves toward the regular position on the first CD holding / transporting member 21, the outer peripheral edge of the leading end of the first CD 8 becomes the third and fourth chucking pins 33,
34, and thereafter, the first and second chucking pins 31, 32 move in the closing direction while abutting on the outer peripheral edge of the CD, and the third and fourth chucking pins 33, 34 move outside the CD with which they abut. It moves while being pushed open by the periphery.

As shown in FIG. 18C, the first CD8
Abuts the positioning portion 25a 'of the guide rail 25a,
When the first CD 8 reaches the regular position on the first CD holding / transporting member 21, the first CD 8 at this time is detected by the photo sensor for position detection, and the CD position detection signal is input to the microcomputer. Stop. Thus, the first
Is set at the regular position on the first CD holding / transporting member 21, and the first CD 8 is set at the store position A.
In the state where the first CD 8 is set at the normal position in this way, the outer peripheral edge of the first CD 8 is positioned between the first and second chucking pins 31 and 32 and the positioning portion 25a '.
The springs 47 and 48 hold the springs. At this time, the outer peripheral edge 8a of the first CD 8 is also held by the third and fourth chucking pins 33 and 34.

When the operation key is turned on, the microcomputer moves the gear 87a of the rack drive gear member 87 to the second rack 8
0 ', and the microcomputer determines that the initial height position of the traverse unit 23 corresponds to the initial height position on the second track side, the microcomputer shifts the power transmission switching arm 94 toward the cam member 89. The first motor is driven to rotate.

When the gear 95 of the power transmission switching arm 94 meshes with the gear 126 which is always meshed with the gear 89d of the cam member 89, the power transmission switching arm 94 does not rotate any more, and the gear 95 rotates the first motor. It rotates more slowly. Then, the rotation of the gear 95 causes the cam member 89 to rotate, and the disc change device operates. By the operation of the disc change device, the gear 87a of the rack driving gear member 87 meshes with the first rack 80, and the initial height position of the traverse unit 23 is switched to a position corresponding to the first track side.

When the gear 87a of the rack drive gear member 87 meshes with the first rack 80 and the initial height of the traverse unit 23 corresponds to the initial height of the first track, the cam position detecting photosensor Cam member 8
9 and detects the rotational position and inputs the position detection signal to the microcomputer. Based on this position detection signal, the microcomputer stops the first motor and drives the second motor to rotate in the direction in which the first rack slider 79 moves from the initial position toward the first CD insertion / ejection port 10.

Thereafter, in the same manner as described above, the first CD 8 is moved to the first CD holding / transporting member 21 as shown in FIG.
The first CD 8 is set at the upper regular position, and the outer peripheral edge of the first CD 8 is held by the first and second chucking pins 31 and 32.

Next, the user inserts the second CD 9 into the second CD.
When the operation key on the second track 7 side is turned on to insert from the insertion / extraction opening 11, the second CD holding / transporting member 21 'in which the second CD 9 is located at the store position A in the same manner as the first track 6 side. Is set to the normal position. As a result, the second CD 9 is set at the store position A.

On the other hand, the user first sets the second CD insertion / extraction port 11 out of the first and second CD insertion / extraction ports 10 and 11.
Also, the case where the second CD 9 is inserted into the first CD 8 and then the first CD 8 is inserted into the first CD insertion / extraction port 10 is the same as the above-mentioned case. The track side component and the second track side component are interchanged). In addition, the user may select the first and second CDs.
There is a case where a CD is inserted into only one of the insertion openings 10 and 11, and in that case, it goes without saying that the operation by inserting a CD into the other CD insertion opening is not performed.

Next, the first and second CDs are
8, 9 are the first and second CD holding and conveying members 21,
The user operates the operation keys of an operation unit (not shown) provided on the apparatus main body 2 in the state where the user has set each of the normal positions on the first 21 'and the first and second CDs 8, 9 have been recorded. From a predetermined number of songs, a desired song is selected and set in the order in which the desired number of songs are heard. The selected songs and the set listening order of those songs are input to the microcomputer.

Then, the microcomputer sets the current initial height position of the traverse unit 23 and the track side corresponding to the CD on which the tune first heard by the rack drive gear member 87 (hereinafter referred to as the first tune) is recorded. Determine if they match. If the microcomputer determines that both of them match the track side corresponding to the first music side CD, the microcomputer controls the second motor to operate the track side rack slider (hereinafter, the first music side rack slider 79, 79 '). (That is)

Clamping and unclamping of D8 and D9 can be performed automatically and reliably.

Further, in conjunction with the setting of the initial height setting position of the traverse unit 23 by the disc change device, the first and second positions corresponding to the set initial height position are set.
Since the drive system (drive system for the second motor) of the CD holding and conveying members 21 and 21 ′ is set, the first and second CD holding and conveying members corresponding to the set initial height position of the traverse unit 23 are set. 21, 21 'can be moved to the pickup position B. Therefore, the desired CD can be reliably picked up without causing the moving first and second CD holding / transporting members 21 and 21 'and the first and second CDs 8 and 9 thereon to interfere with the traverse unit 23. The position B can be set.

Further, the first and second positions at the store position A are
The first and second CDs 8 and 9 held by the CD holding and conveying members 21 and 21 ′ are pushed out by the CD pushing mechanism 57 toward the first and second rollers 17 and 18, respectively. Since the first and second CDs 8, 9 are ejected to the outside of the apparatus main body 2 by the two rollers 17, 18, the CD in the apparatus main body 2 can be automatically and reliably ejected.

Further, the first and second CD holding and conveying members 2
When the first and second CDs 8 and 9 are held in the respective CD insertion slots (10, 1 '),
1) is closed by the shutters (13, 14), so that the CD (8, 9) is inserted into the CD insertion / extraction opening (10, 1).
You can recognize that it is already inserted from 1),
It is possible to prevent erroneous insertion of the CD (8, 9).

FIG. 25 is a view similar to FIG. 5B, showing a first CD holding / transporting member in another embodiment of the disk recording medium processing apparatus according to the present invention. As shown in FIG. 25, even in the disk recording medium processing device of this example,
The first to fourth pin support plates 35, 3 are similar to the above-described respective examples.

6, the third and fourth chucking pins 33, 34 are connected to the first and second chucking pins 31, 32.
It operates in synchronization with. In this case, in detail, the lever 37 of the third pin support plate 37 is loosely fitted in the concave groove 54a of the cam hole 54 with a predetermined gap between the lever 37 and the side wall of the concave groove 54a, and the CD 8 is inserted. The first and second chucking pins 31 and 32 are expanded to
After the chucking control member 51 slightly rotates counterclockwise in FIG. 25, the side wall of the concave groove 54a comes into contact with the lever 37, and the third chucking pin 33 is connected to the first and second chucking pins 31, 32. It works synchronously.

Further, in this example, in the state where the CD 8 is set at the normal position, the first to fourth signals are set in the same manner as in the above-described examples.
The chucking pins 31, 32, 33, and 34 hold the outer peripheral edge of the CD 8 and chuck. At this time, the first to fourth chucking pins 31, 32, 33, 34
Are located at 12 cm C as shown in FIG.
At D8, positions 31 (a), 32 (a), 33 (a), 34
(A), and at 8 cm CD8, positions 31 (b), 3
2 (b), 33 (b) and 34 (b). At this time, in cooperation with the cam pins 46 of the fourth pin support plate 38 and the concave grooves 55a, the fourth pin support plate 38
Is prevented from rotating further counterclockwise from the position corresponding to the normal position. Thus, the fourth chucking pin 34 functions to position the CD 8 at the normal position by preventing the CD 8 from being inserted beyond the normal position. Therefore, in this example, the CD positioning portions 25a ',
26a 'is omitted. Other configurations and other operational effects of this example are substantially the same as those of the above-described example.

FIG. 27 is a view similar to FIG. 25, showing a modification of the first CD holding / transporting member shown in FIG. In addition,
FIG. 27 is upside down from FIG. In each of the above-described examples, the first and second chucking pins 31, 32 move in an arc shape by rotating the first and second pin support plates 35, 36. Then
